v2.6 rc4
If I put the tx frequency higher than ~2700Hz I have no audio output.
I'm using split = none, data/pkt mode; the output frequency is under my control (i'm working on QO-100 with separate devices in tx and rx, so i manually adjust the frequency output on the tx rig)
When I change output freq (with shift click on the warefall) the audio come back.

Waterfall screenshot (after a shift click that cancelled the audio output):
